Had the same issue with openSUSE in virtualbox. turning 3d acceleration off fixed it for me if it helps. Still wondering tho why it did.

The section control technology youre refering to is already being used in some countries, and they ofcourse automatically send you your speeding tickets. 3-5 mph would only be a marginal fine tho, if there even would be a fine at all. I dont understand though how that would be any different from normal speed checks, except for the fact that it might be more accurate.
